Similar reference characters designate cor- An auxiliary drive shaft D' comprising an en- 55 larged central portion I and reduced end portions 52 and 53, is rotatably supported at opposite ends in the housing 30 by anti-friction bearings 5I and 55. The bearing 54 is enclosed by a co-ver plate 35 secured to the housing 30 by bol s Iii). The rear end 53 of the shaft 59 projects through the housing 30 and is adapted, at its outer end, to have a drive take-off illustrated as a sprocket wheel 56 secured thereto. An oil retainer 51, supported in a member 58 secured to the housing 33 by means of bolts 59, prevents leakage of oil in the opening through which the shaft D projects. A gear cone 60, consisting of integrally formed gears 6I and 62, is keyed as by the key 39, to the enlarged portion 5I of the shaft D. A second gear cone 63, consisting of integrally formed gears 64 and 65, is rotatably supported on the shaft D by means of roller bearings 66 and ball bearings 61. The gear 64 of the gear cone 63 is continuously in mesh with the gear 69 rotatably supported on the shaft C, and the gear 65 is continuously in mesh with a gear 69 formed integral with the shaft D. The shaft C is adapted to be connected to the gear 68, or direct to the shaft D, by means of a clutch designated inv general by the reference character E, comprising a member 'Ill spiined to a section 29 of the shaft C and held in position thereon against a shoulder 29 by a spring lock 80. A member TI splined to the member '16, is adapted to be moved axially thereof, by a yoke member 72, to engage a clutch element I3 formed integral with the gear 68 or a clutch element i4 formed integral with the shaft D.

A reversing gear 'I5 rotatably supported on a fixed shaft 'i6 by means of anti-friction bearings 'l1 is continuously in mesh with the gear 6I of the gear cone 69. The shaft 'i6 has a head I8 formed integral therewith and is supported in a suitable aperture in the housing 36. A lock member 19, secured to the housing by a bolt 89, projects into a groove in the shaft i6 and retains the same in position. A gear 65, splined to a section 35 of the shaft C, is adapted to be moved axially of said shaft, by the yoke member ill, in either direction from its neutral position illustrated in Fig. 5, to engage the reverse gear I5 or the gear 62 of the gear cone 66. whereby the shaft D may be driven in either direction and preferably at different speeds. The yoke member l2 which engages in a groove 98 in the clutch member II is fixed to a longitudinally reciprocable shaft 99, slidably supported in suitable bearings in the housing 39, and the yoke member 8'I which engages in a groove 9I in the hub of the gear 85 is xed to a similar shaft 94 slidably supported in the housing 30. Spring pressed plungers 95 and 96, adapted to engage suitable grooves 9i' in the shafts 9D and 9,retain said shafts in predetermined positions with the elements controlled thereby in their neutral or either of their engaged positions.

The shafts 9D and 9d are reciprocatedlongitudinally to move the clutch member 'II and the gear 85 by mechanism (not shown) located in the cab of the vehicle and connected to eyes 98 and 99 formed in the ends of said shafts.

The universal joint 23 is bolted or otherwise secured to a disk member Ill5 keyed to a spline section |06 of the shaft C and retained thereon by the nut Iil'l. A disk member IIU keyed as by sleeve 42 by bolts II9, is adapted to be applied thereto by means o f a hand lever |20 located in the control cab of the vehicle and connected thereto by a brake rod I2I. The reference character |22 designates a flexible speedometer shaft operatively connected to a gear on the shaft D.

From the foregoing description it will be apparent that the driving shaft C is driven from the transmission I 6 through the front propeller shaft .2| and may be operatively connected to the auxiliary drive shaftvD' through the gear 85 and the gear cone 60, or to the driven shaft D through the gear 68, the gear cone 63 and the gear 69, or directly connected thereto, by means of the clutch E, and that the auxiliary drive shaft D' may be driven in opposite directions through the reverse gear or the gear 62 and preferably at different speeds.

It will be noted that the brake drum SI2 is supported by the shaft D of the auxiliary transmission B, which permits the brake II1 to be applied thereto and the motor vehicle held stationary while the auxiliary drive is being operated.

The invention has been described with reference to the preferred embodiment thereof, but it is understood that it is susceptible of numerous constructions and we do not wish to be limited to the particular construction illustrated, and particularly point out and claim as our invention.
